Flushing Guidance

Fond du Lac Water Utility is advising businesses and other water customers about the importance of following procedures when reopening a location where water has been stagnant in pipes.

Plumbing systems that were inactive for an extended period, such as during the shutdown for the Coronavirus (COVID-19) pandemic, can pose a health risk. Water that has not been circulated can create a potential for pathogen growth because the disinfectant in the water will dissipates over time. This stagnant water can allow disease causing pathogens to grow within the water pipes.

As some businesses start re-opening, it is recommended to follow the listed steps to maintain water quality. The purpose of building flushing is to replace ALL water inside building piping with fresh water, not just drinking water.

  • Flush hot and cold water through all points of use (e.g. showers, sink faucets, appliances, icemakers, hot water heaters, drinking fountains, etc.)
    • Flush cold water lines before hot water lines.
    • Flushing may need to occur in segments, depending on size of individual rooms or if a building contains multiple floors.
    • Flushing should start at the lowest level, the one nearest to the building’s water supply.
    • Replace all point-of-use filters, including filters in refrigerators.
